Smoking pipe

Z/LPezersan ATI'D RN EYS Patented Sept. 25, 1951 UNITED T FICE Thesaliva from the mouth of the smoker has always been objectional in thatit will flow down the stem of the pipe into the bowl, or will mix withthe tobacco juices in pipe tobacco and will return to be sucked into themouth of the smoker causing a most unpleasant sensation. In coldclimates it has been found that the saliva flowing into the stem hasfrozen and prevented the proper functioning of the pipe until the frozenmoisture is thawed, or the moisture removed by continually shaking thepipe to remove the saliva.

In the accompanying drawings I have disclosed one complete example ofthe physical embodiment of my invention according to the best mode Ihave thus far devised but it will be understood that various changes andalterations may be made in the exemplified structure within the scope ofthe appended claim.

In the drawings:

Figure 1 is a side elevational view of the pipe of my invention.

Figure 2 is a top plan view thereof.

Figure 3 is a vertical longitudinal sectional view.

Figure 4 is a transverse vertical sectional view taken at line 4-5 ofFigure 3.

Figure 5 is an enlarged fragmentary sectional view showing certainconstructional details of the pipe;

Figure 6 is an enlarged fragmentary sectional view showing the portionof the pipe which is inserted in the smokers 'rnouth.

Referring now to the drawings wherein like characters indicate likeparts I have illustrated a smoking pipe having a body 2 and a bowl 4.The bowl 4 is integral with the body and is formed-with thickened walls5. An ash receptacle S is shown forward of the bowl and this rec eptacIein the base of the bowl to prevent the passage therethrough of ashes andbits of tobacco, and

the stem 12 of the pipe being connected with the base of the bowl isfashioned with a bit I i. A ring 26 serves to maintain the screen in itsproper place in the bowl.

In order to prevent the flow of saliva from the bit through the stem, Iprovide an open-ended tube of copper or aluminum, or other suitablematerial as It through the thickened wall 5 of the bowl into and throughthe hollow stem and through the bit I4.

This tube terminates at l8 exteriorly of the wall 5 of the bowl 4 andabove the ash receptacle 6. This tube It is the only passage through thebit, and the smoke from the burning tobacco is drawn by suction throughthe screen into the stem and thence through a port or aperture 22 intothe tube and thus through the bit.

Vents 20 in the tube It communicate with vents 25 in the wall 5 of thebowl to permit the escape of heated moisture in the tube and themoisture is substantially vaporized due to the location of the tube atthe hottest part of the pipe, i. e., in the wall of the bowl.

I also employ within the tube It a tufted wire similar to theconventional pipe cleaner and illustrated as at 2 to absorb and collectmoisture and juices therein.

The tube being of copper or aluminum will be an efiicient means oftransferring heat from the smoke in the stem to the exterior of the pipeand will result in a cleaner cooler smoke without the unpleasant salivaflow into the bowl. The normal passage of smoke is through the screen10, into chamber 29, thence through aperture 22, and into tube It,whereby the smoke can be drawn into the smokers mouth. Any saliva thatcollects in the bend of the tube Iii can be brought into contact withthe member 24 by tilting the pipe, the member 24 absorbing or retainingthis fluid, and the saliva in the tube I6 will be vaporized by heat fromthe hot smoke, as well as by heat transfer from the burning tobacco. Inother words, the burning tobacco will heat the adjacent portion of thepipe bowlso that the vaporized saliva passes out through the vents 20and 25. The aperture 22 is of sufiicient diameter that saliva will notblock this aperture.

Having thus fully described my invention what I claim as new and desireto secure by Letters Patent is:

In a smoking pipe, the combination with a bowl, an open-ended receptaclefor containing ashes arranged forwardly of said bowl, a stem arrangedrearwardly of said bowl, and a bit extending from an end of said stemadapted to be inserted in the smokers mouth, of a means for preventingthe fiow of saliva from the smokers mouth from contacting with theinterior of the stem, said means comprising an open-ended tube arrangedlongitudinally in said pipe, an end of said tube extending through saidbit, and the other end of said tube terminating above said rece'ptacle,an intermediate portion of said tube passing through a wall of said bowland supported by said wall, there being an aperture arranged in saidtube for the ingress therethrough of smoke, and means for absorbingfluid in said tube.
